Petunia plant named ‘DCAS303’

ABSTRACT

A new and distinct  Petunia  cultivar named ‘DCAS303’ is disclosed, characterized by abundant flowering, unique flower coloration, which changes with maturity, strong vigor and a very well branched plant with a semi-trailing form. The new variety is a  Petunia , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Petunia sensu wijsman.

Variety denomination: ‘DCAS303’.

BACKGROUND OF THE INVENTION

The new Petunia cultivar is a product of a planned breeding program conducted by the inventor, Gavriel Danziger, in Moshav Mishmar Hashiva, Israel. The objective of the breeding program was to produce new Petunia varieties for ornamental commercial applications. The cross resulting in this new variety was made during October of 2010.

The seed parent is the unpatented, proprietary variety referred to as Petunia sensu wijsman. ‘cv. 7-1380’. The pollen parent is the unpatented, proprietary variety referred to as Petunia sensu wijsman ‘cv. 10-4341’, containing the black gene described in U.S. Utility Pat. No. 7,642,436. The new variety was discovered in June of 2011 by the inventor in a group of seedlings resulting from the 2010 crossing, in a research greenhouse in Moshav Mishmar Hashiva, Israel.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in Moshav Mishmar Hashiva, Israel in July of 2011 and has shown that the unique features of this cultivar are stable and reproduced true to type in more than 25 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DCAS303’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DCAS303’ These characteristics in combination distinguish ‘DCAS303’ as a new and distinct Petunia cultivar:

-   -   1. Semi-trailing growth habit.     -   2. Very well branched plants with strong vigor.     -   3. Flowers change color from yellow when opening to orange-pink,         fading to pink-brown.     -   4. Large flower size.     -   5. Abundant flowering.

PARENT COMPARISON

Plants of the new cultivar ‘DCAS303’ are similar to plants of the seed parent, Petunia sensu wijsman ‘cv. 7-1380’ in most horticultural characteristics, however, plants of the new cultivar ‘DCAS303’ differ in the following:

-   -   1. Semi-trailing growth habit compared to the semi upright         growth habit of the seed parent.     -   2. Larger plant size     -   3. Different flower color during various stages: yellow when         opening to orange-pink, fading to pink-brown compared to pink         color of the seed parent.     -   4. Larger flower size.     -   5. Greater amount of flowers.

Plants of the new cultivar ‘DCAS303’ are similar to plants of the pollen parent; Petunia sensu wijsman ‘cv. 10-4341’ in most horticultural characteristics, however, plants of the new cultivar ‘DCAS303’ differ in the following;

-   -   1. Semi-trailing growth habit compared to the trailing growth         habit of pollen parent.     -   2. Many more branches per plant than the pollen parent.     -   3. Changing flower color, yellow when opening to orange-pink,         fading to pink-brown compared to black with yellow striped         flower color of pollen parent.     -   4. Smaller flower size.     -   5. Less abundant flowering.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DCAS303’ are comparable to the commercial variety Petunia ‘DANRAY1’ U.S. Plant Pat. No. 20,974. The two Petunia varieties are similar in most horticultural characteristics; however, the new variety ‘DCAS303’ differs in the following:

-   -   1. Smaller flower size.     -   2. Yellow-orange-pink flowers. The comparator has white flowers.     -   3. Semi-trailing growth habit compared to the mounded growth         habit of the comparator.

Plants of the new cultivar ‘DCAS303’ can also be compared to the commercial variety Petunia ‘DANRAY3’, unpatented. These varieties are similar in most horticultural characteristics; however ‘DCAS303’ differs in the following:

-   -   1. Smaller flower size.     -   2. Yellow-orange-pink flowers. The comparator has light purple         flowers with dark purple veins.     -   3. Semi-trailing growth habit compared to the mounded growth         habit of the comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DCAS303’ grown in a greenhouse, in a 13 cm pot. Age of the plant photographed is approximately 3 months from a rooted cutting.

FIG. 2 illustrates in full color a close up of a typical bloom of ‘DCAS303’. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
